Question
I need help finding initial ke, and final ke.
The Experiment: In this experiment, the muzzle velocity of a projectile launcher will be 1) predicted, 2) measured, and 3) used as an initial parameter to attempt to land a ball on a floor target. 1. Remove the ball from the bob and reset the maximum height rule. Place the ball into the gun and load the gun by pushing the ball down the muzzle using the dowel. Remember to be consistent with your setting. 2. When the pendulum is at rest, fire the ball into the pendulum bob. This will cause the pendulum with the ball inside it to swing up and strike the marker and the highest angle that the bob has swung. Record this angle and repeat this procedure four times, recording the maximum angle for each trial. 67g 20g Ball Steel Plastic 0₁ 37.5 15.0 Table 4: Record experimental data below. 02 03 38.2 38.0 14.3 13.5 04 38.6 14.5 Ave. Deflection 38.1 14.3 arm mass: 243g arm length: 30cm 3.
